OIL DRAIN.

Application filed July 8, 1927. Serial No. 204,350.

' This invention relates to improvements in oil drains whichembodiesamong other ch aracteristics a construction permitting drainsfor reservoirs to be controlled at remote points.

Another object of the invention comprehends a depth gage operable inconjunction with theoil drain. a

A further object of the invention contemplates a handle member for theoil drain.

More specifically stated the oil drain is adapted to receive the gage.

Said drain is furthermore provided with openings to permit the'contentsof the reservoir to seek its level therein whereby the oil level of thereservoir may be readily determined upon the withdrawal ofithe gagefrom. the drain.

With the above and other objects in view, the invention further consistsof the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawing and. pointed out in the appended claim.

In the drawing: I

Figure 2 is a longitudinal sectional view of the invention per se. YFigure 3 is a sectional 33 of Figure 1'.

Referring to the drawing in detail, wherein like characters of referencedenote corresponding parts, the reference character 10 indicates thecrank case of an internal comview taken on line bustion engine having anoil pan 11, the above being of the usual construction as embodied in thecrank cases of motors of the character described.

It is generally known in the construction of the particular type ofmotor,aforementioned, that the most effective and reliable oil gage isthat of a thin strip extended -with- -in the crank' case, the oil levelwithin the crank case will be indicated upon the strip.

In carrying out the invention" it is mycardinal purpose to utilize theaforementioned tvpe of gage 12 and to combine therewith a housing,member therefor such as indicated at 13, closed uponone end and providedwith a threaded extension 14 adapted for engage ment within a drainopening 15 within the bottom of the pan 11 and disposed in alignmentwith the opening in the crank case. Said housing 13 is provided withhandle portions 16 to permit the same to be easily rotated in eitherdirection. When the threaded extension 14 is removed from the opening 15the contents of the .crank case will be drained, thereby obviating theusual necessity of crawling beneath a motor vehicle and loosen-- ing acap screw to accomplish this purpose which often provesdisastrous in theevent that the oil finds its way up the sleeve. The gage 12 is providedwith a knob 17 upon the outer extremity thereof and a tapered portion 18disposed within a seat 19 having communication with the bore of thehousing 13.

An enlargedportion 20'provided adjacent the outer end of the housing isadapted to strengthen the same at the point wherein the same will morefrequently rub or chafe against the walls of the opening in the crankcase. The lower portion of the housing is furthermore provided with amultiplicity of openings 21 having communication with the bore thereofin order that contents of the pan 11 may seek its level within thehousing. The gage 12 when removed from the housing will indicate the oillevel within the crank case. It is thus to be noted that essential andeffective means have been combined to produce an oil drain capable ofbeing operated at a remote point from the oil drain in the crank caseand of the gage operable in conjunction therewith. The constructioninvolved will permit the same to be manufactured at small cost and henceappear upon different makes of automobiles as a decided improvement andsales getter. j

The invention vis susceptible ef various changes in its form,proportions 'and minor details of construction and the right is hereinreserved to make such changes as properly fall within the scope of theappended claim.

Having thus described the invention, what is claimed is! An oil drainand gauge for use within the crank case of an internal combustion enginecomprising a tubular member having perforations in the periphery thereofadjacent one end, said tubular member having a closed end adjacent saidperforations having-screw threads on the periphery thereof whereby saidend may be fitted into the drain opening" in the crank case, saidtubular member having an enlarged portion on the periphery thereof atthe endthereo'f opposite said end having said enlarged end may beextended through lar member having a conical portion on the an openingin the upper portion of said crank outwardly disposed end thereofwhereby said case, a handle fitted at the outer end of said conicalportion may be seated on said valve 10 enlarged portion, said tubularmember havseat to retain said gauge in said tubular mem- 6 ing a taperedportion on the inner periphery ber.
